Saikkonen (1991) developed an asymptotic optimality theory for the estimation of cointegrated regressions. He proposed the dynamic OLS estimator obtained by augmenting the static cointegrating regression with leads and lags of the first differences of the I(1) regressors. However, the...

In summary, the effects of decentralization on corruption and government accountability are complex and cannot be summarized by simple, unconditional statements. This applies equally to theoretical analyses, cross-country regression results and more detailed empirical studies of specific...

Regional inequality is severe in China since regional development is uneven due to various initial conditions and government policies. We employ unit root tests allowing for structural breaks to alternative inequality measures from 1952 to 2000. Empirical results indicate that (1) the regional...

This paper considers various asymptotic approximations to the finite sample distribution of the estimate of the break date in a simple one-break model for a linear trend function that exhibits a change in slope, with or without a concurrent change in intercept. The noise component is either...

In a financial market where agents trade for short-term profit and where news can increase the uncertainty of the public belief, there are strategic complementarities in the acquisition of private information and if the cost of information is sufficient small, a continuum of equilibrium...

I derive a production-based asset pricing formula to infer aggregate stock market returns from macroeconomic time series when the technology is putty-clay. Capital heterogeneity leads to variation in the aggregate stock market value through a new compositional effect. The asset pricing formula,...

In their debate article, Andrew Street and Alan Maynard highlight the problems with using average cost pricing for hospital payments in the English National Health Service, pointing out that lack of cost containment and failure to improve quality are potential weaknesses. In this invited comment...

This paper specifies and estimates a dynamic model of consumer preferences for new durable goods with persistent heterogeneous consumer tastes, rational expectations about future products and repeat purchases over time. Most new consumer durable goods, particularly consumer electronics, are...
